Common Problems with Air PreheatersThe air preheater refers to the heating surface that preheats the air to a certain temperature through the internal cooling fins before the flue gas in the tail flue of the boiler enters the boiler. It is a device that improves the heat transfer performance of the

Gas plate heat exchanger (gas heat exchanger) and residual heat recycling1. The air heat exchanger is mainly plate heat exchanger. Compared with the tube heat exchanger, the heat transfer coefficient of the plate -type heat transfer device increases by 50%-200%, and the steel saves 50%-70%, accounti

A large amount of air needs to be consumed in the combustion process of the boiler. Before combustion, the air at room temperature needs to be heated to about 300 ℃, and then the air participates in the combustion. The heating process of the air also consumes a part of the fuel combustion energy.Aft

The air preheater is a kind of preheating equipment that improves the heat exchange performance of the boiler and reduces the heat loss. The function of the air preheater is to conduct the heat carried in the flue gas discharged from the flue at the tail of the boiler to the air before entering the
